摘要： A seal ring assembly 400 includes a first seal ring axially disposed from a second seal ring. The first seal ring 412H has an axial face 413 opposing an axial face 414 of the second seal ring 412A. A radial oil channel 405 is defined between the two axial faces. Both seal rings have a tapered surface configured to contact a spring 440. The spring biases the seal rings away from each other via the tapered surface. Both seal rings are disposed in a radially inwardly directed channel. At least one of the seal rings have a plurality of protrusions 460 that extend beyond the axial face. The protrusions are configured to create a passageway to allow oil to flow through the passageway and to allow at least one of the seal rings to move into a desired position by reducing static friction between the axial faces.

摘要： The rotor for an electrical machine comprises a plurality of stacked laminations (415). Each lamination (415) includes a plurality of radially extending slots (140) arranged about a circumference thereof and a first chamfer (520) on a surface (550) of each of the slots (140), wherein the surface (550) mates with a wedge (150). The first chamfer (520) connects the surface (550) and a first face (418) of the lamination (415). Advantage: Avoiding electrical contact between laminations due to smearing when the wedge mating surface (550) of the assembled rotor must additionally be machined.

摘要： A rotor and a dynamoelectric machine including a rotor are disclosed. In an embodiment, the rotor includes a rotor body having a plurality of axially extending slots disposed radially about the rotor body, and at least one coil having at least one turn positioned within each of the plurality of axially extending slots. The rotor further includes a plurality of subslots disposed in the rotor body such that each subslot extends axially through the rotor body parallel to an axis of rotation of the rotor body, and is in fluid communication with a radially inner end of a slot; a passageway extending substantially radially outwardly along each axially extending slot for cooling the at least one turn disposed in the slot; and a retaining member in each of the slots for retaining the at least one turn within the slot. Various embodiments provide ventilation via the passageway for cooling the rotor coils.
